Note that a vehicular display control device 10 is provided to the vehicle 12. The vehicular display control device 10 of the present exemplary embodiment is for example a display electronic control unit (ECU) that performs various controls.

Hardware Configuration of Vehicular Display System S

As illustrated in FIG. 2 , the vehicular display system S is configured including the vehicular display control device 10.

The vehicular display control device 10 is configured including a central processing unit (CPU; processor) 20, read only memory (ROM) 22, random access memory (RAM) 24, storage 26, a communication interface (communication I/F) 28, and an input/output interface (input/output I/F) 30. The respective configuration elements are connected so as to be capable of communicating with one another through an internal bus 32.

The CPU 20 is a central processing unit that executes various programs and controls respective sections. Namely, the CPU 20 reads a program from the ROM 22 or the storage 26, and executes the program using the RAM 24 as a workspace. The CPU 20 also controls the respective configuration elements and performs various arithmetic processing according to the programs recorded in the ROM 22 or the storage 26.

The ROM 22 holds various programs and various data. The RAM 24 acts as a workspace to temporarily store programs or data. The storage 26 is configured by a hard disk drive (HDD) or a solid state drive (SSD), and is a non-transitory recording medium that holds various programs including an operating system, and various data. In the present exemplary embodiment, programs such as a program for performing display processing are held in the ROM 22 or the storage 26.

The communication I/F 28 is an interface enabling the vehicular display control device 10 to communicate with an external server and other equipment, and a standard such as a Controller Area Network (CAN), Ethernet (registered trademark), Long Term Evolution (LTE), Fiber Distributed Data Interface (FDDI), or Wi-Fi (registered trademark) may be employed therefor.

The first right-side operation switch 34R, the second right-side operation switch 36R, the right-side function switchover switch 38R, the first left-side operation switch 34L, the second left-side operation switch 36L, the left-side function switchover switch 38L, the first image display device 40, and the second image display device 42 are electrically connected to the input/output interface 30.

The first image display device 40 is a device for performing a predetermined display on the display region V1 of the meter display. The second image display device 42 is a device for performing a predetermined display on the display region V2 of the head-up display.

The vehicular display control device 10 is electrically connected to a driving assistance ECU 44. As an example, the driving assistance ECU 44 of the present exemplary embodiment performs control such as active cruise control (ACC) and lane tracing assist (LTA). The driving assistance ECU 44 is thereby configured so as to be capable of acquiring signals from various sensors that detect the surroundings of the vehicle 12.

The vehicular display control device 10 implements various functionality using the above-described hardware resources. Explanation follows regarding functional configuration implemented by the vehicular display control device 10, with reference to FIG. 3 .

As illustrated in FIG. 3 , the vehicular display control device 10 is configured including as functional configuration a right-side operation detection section 50, a left-side operation detection section 52, a vehicle status acquisition section 54, an operation region image display section 56, and a status image display section 58. Note that the respective functional configuration is implemented by the CPU 20 reading and executing a program stored in the ROM 22 or the storage 26.

The right-side operation detection section 50 detects when the right-side operation region has been operated. Specifically, the right-side operation detection section 50 detects when any switch out of the first right-side operation switch 34R, the second right-side operation switch 36R, or the right-side function switchover switch 38R has been operated. Note that here “operation” includes not only an action by the occupant to press a switch, but also includes an action by the occupant to touch a switch. Thus, for example, the right-side operation detection section 50 detects when the occupant has touched the first right-side operation switch 34R using a signal from the corresponding static sensor. The right-side operation detection section 50 also detects when the occupant has pressed the first right-side operation switch 34R using a signal or the like from a corresponding pressure sensor.

The left-side operation detection section 52 detects when the left-side operation region has been operated. Specifically, the left-side operation detection section 52 detects when any switch out of the first left-side operation switch 34L, the second left-side operation switch 36L, or the left-side function switchover switch 38L has been operated. Thus, for example, the left-side operation detection section 52 detects when the occupant has touched the first left-side operation switch 34L using a signal from the corresponding static sensor. The left-side operation detection section 52 also detects when the occupant has pressed the first left-side operation switch 34L using a signal or the like from the corresponding pressure sensor.

The vehicle status acquisition section 54 acquires vehicle statuses based on signals detected by various sensors. For example, the vehicle status acquisition section 54 acquires statuses of onboard equipment installed to the vehicle 12. Here, “onboard equipment” includes an air conditioner, an audio system, and the like. The vehicle status acquisition section 54 also acquires statuses relating to driving assistance functions of the vehicle 12.

In cases in which operation of the right-side operation region has been detected, the operation region image display section 56 displays a right-side operation region image corresponding to the right-side operation region in a right-side area of the display region V2. Similarly, in cases in which operation of the left-side operation region has been detected, the operation region image display section 56 displays a left-side operation region image corresponding to the left-side operation region in a left-side area of the display region V2. The operation region image display section 56 also performs emphasized display of a portion corresponding to the switch that the occupant is touching. Furthermore, in cases in which operation of either the right-side function switchover switch 38R or the left-side function switchover switch 38L has been detected, the operation region image display section 56 displays an animation in which the operation region image is flipped over.

The status image display section 58 displays a current status of the function allocated to the switch that is being operated on the display region V2. The status image display section 58 also changes this status image according a change in the status due to operation of the operation region. Explanation follows regarding functionality of the operation region image display section 56 and the status image display section 58, with reference to FIG. 4 to FIG. 9 .

A right-side status image 70M is displayed on the right side of the left-side operation region image 64M using the functionality of the status image display section 58. Text indicating that this is an air conditioner airflow setting screen is displayed at an upper portion of the right-side status image 70M. An icon representing a fan is displayed below the text.

A substantially bar-shaped icon that extends along the left-right direction is displayed at a lower portion of the right-side status image 70M. The icon has a tapered shape that becomes narrower in width on progression from the right side toward the left side. Only the left half of the bar-shaped icon is displayed in color, thereby enabling the occupant to intuitively ascertain the current airflow of the air conditioner. A minus sign is displayed on the left side of the bar-shaped icon, and a plus sign is displayed on the right side of the bar-shaped icon.

If the occupant presses the right portion of the first left-side operation switch 34L following on from the state in FIG. 5 , an increase in the air conditioner airflow is executed. When this occurs, the right-side status image 70M is changed in the manner illustrated in FIG. 6 using the functionality of the status image display section 58.

As illustrated in FIG. 6 , a colored region of the bar-shaped icon in the right-side status image 70M has increased compared to FIG. 5 . Specifically, a portion of the bar-shaped icon further toward the right side than a halfway point is colored, thereby enabling the occupant to visually confirm that the air conditioner airflow has increased. Note that although the portion indicating the increased airflow is depicted in a different color for ease of explanation in FIG. 6 , there is no limitation thereto, and the entire colored region may be displayed in the same color.

In cases in which the occupant has touched any switch out of the first right-side operation switch 34R, the second right-side operation switch 36R, or the right-side function switchover switch 38R following on from the state in FIG. 4 , a transition is made to the state illustrated in FIG. 7 . As illustrated in FIG. 7 , a right-side operation region image 62M is displayed in a right-side end area of the display region V2 using the functionality of the operation region image display section 56. Note that the operation region image display section 56 moves the central image 60M toward the left side from its position in FIG. 4 , and displays the right-side operation region image 62M further toward the right side than the central image 60M.

The right-side operation region image 62M is configured including a first right-side operation switch image 34RM with a shape representing the first right-side operation switch 34R, a second right-side operation switch image 36RM with a shape representing the second right-side operation switch 36R, and a right-side function switchover switch image 38RM with a shape representing the right-side function switchover switch 38R. FIG. 7 illustrates a state in which the occupant is touching the right-side function switchover switch 38R.

As an example, icons are not displayed at an upper portion and a right-side portion of the first right-side operation switch image 34RM. Namely, the design is such that no icon is displayed at a location where no function has been allocated.

An icon relating to setting inter-vehicle distance is displayed at a left-side portion of the first right-side operation switch image 34RM. When this icon is selected, the inter-vehicle distance can be set. Namely, an inter-vehicle distance setting function has been allocated to the left-side portion of the first right-side operation switch 34R.

As illustrated in FIG. 8 , the second right-side operation switch image 36RM and the right-side function switchover switch image 38RM do not change, and only the first right-side operation switch image 34RM is flipped over.

As illustrated in FIG. 9 , when the first right-side operation switch image 34RM has been flipped over, the functions allocated to the first right-side operation switch 34R have changed. Namely, the icons displayed at the upper, lower, left, and right sides of the first right-side operation switch image 34RM have changed.

Next, explanation follows regarding operation of the present exemplary embodiment.

Explanation follows regarding an example of display processing by the vehicular display control device 10, with reference to the flowchart illustrated in FIG. 10 . The display processing is executed by the CPU 20 reading a display program from the ROM 22 or the storage 26, and deploying and executing the display program in the RAM 24.

At step S102, the CPU 20 acquires an operation situation of each of the operation regions. Specifically, the CPU 20 acquires information from the non-illustrated static sensors that are respectively installed to the first right-side operation switch 34R, the second right-side operation switch 36R, the right-side function switchover switch 38R, the first left-side operation switch 34L, the second left-side operation switch 36L, and the left-side function switchover switch 38L.

At step S104, the CPU 20 determines whether or not the hand of the occupant is contacting the right-side operation region. Specifically, in cases in which the CPU 20 has detected using the functionality of the right-side operation detection section 50 that the hand of the occupant is contacting any switch out of the first right-side operation switch 34R, the second right-side operation switch 36R, or the right-side function switchover switch 38R, step S104 is affirmative and processing transitions to step S106. On the other hand, in cases in which the CPU 20 has not detected using the functionality of the right-side operation detection section 50 that the hand of the occupant has contacted any switch out of the first right-side operation switch 34R, the second right-side operation switch 36R, or the right-side function switchover switch 38R, step S104 is negative and processing transitions to step S110. The processing of step 5110 onward is described later.

At step S106, the CPU 20 uses the functionality of the operation region image display section 56 to move the central image 60M toward the left side. At step S108, the CPU 20 displays the right-side operation region image 62M and the left-side status image 72M in the display region V2 (see FIG. 7 ).

On the other hand, in cases in which the hand of the occupant has not contacted the right-side operation region, at step S110, the CPU 20 determines whether or not the hand of the occupant has contacted the left-side operation region. Specifically, in cases in which the CPU 20 has detected using the functionality of the left-side operation detection section 52 that the hand of the occupant is touching any switch out of the first left-side operation switch 34L, the second left-side operation switch 36L, or the left-side function switchover switch 38L, step S110 is affirmative and processing transitions to step S112. On the other hand, in cases in which the CPU 20 has not detected using the functionality of the left-side operation detection section 52 that the hand of the occupant has contacted any switch out of the first left-side operation switch 34L, the second left-side operation switch 36L, or the left-side function switchover switch 38L, step 5110 is negative and the display processing is ended.

At step 5112, the CPU 20 uses the functionality of the operation region image display section 56 to move the central image 60M toward the right side. At step S114, the CPU 20 displays the left-side operation region image 64M and the right-side status image 70M in the display region V2 (see FIG. 5 ).

As described above, in the vehicular display control device 10 according to the present exemplary embodiment, in cases in which an operation region provided to the steering wheel 16 has been operated, an operation region image corresponding to this operation region is displayed in the display region V2 set in front of the driving seat. A status image indicating the current status of the function allocated to the switch that is being operated is also displayed in the display region V2. This enables the occupant to ascertain the current situation of the function without having to view another display or the like.

In particular, since the display region V2 is set on the windshield glass 17 in the present exemplary embodiment, the operation region image and the status image can be visually checked in a state in which the occupant is directing their gaze toward the windshield glass 17.

Moreover, in the present exemplary embodiment, the occupant can ascertain that a status has changed simply by viewing the corresponding status image. Furthermore, the occupant can identify the switch that they are touching simply by looking at the portion with the emphasized display. There is accordingly no need for the occupant to lower their gaze in order to visually check the actual switch.

Furthermore, in the present exemplary embodiment, the occupant can ascertain the status of the onboard equipment simply by looking at the right-side status image 70M displayed in the display region V2. Similarly, the occupant can ascertain the status of the driving assistance function simply by looking at the left-side status image 72M displayed in the display region V2.

Moreover, in the present exemplary embodiment, when the functions of the first right-side operation switch image 34RM are switched as illustrated in FIG. 7 to FIG. 9 , the first right-side operation switch image 34RM displayed in the display region V2 appears to flip over from the perspective of the occupant, thereby enabling the occupant to intuitively realize that the functions allocated to the first right-side operation switch image 34RM have changed. Moreover, the occupant can intuitively realize that the first right-side operation switch image 34RM can be flipped over again and returned to its original state by operating the right-side function switchover switch 38R again.

Although the vehicular display system S and the vehicular display control device 10 according to the present exemplary embodiment have been described above, obviously various modifications may be implemented within a range not departing from the spirit of the present disclosure. For example, although an example of display in the display region V2 has been described in the above exemplary embodiment, there is no limitation thereto, and the corresponding right-side operation region image or left-side operation region image may be displayed in the display region V1.

Moreover, although only the first right-side operation switch image 34RM is displayed as an animation that is flipped over as illustrated in FIG. 7 to FIG. 9 in the above exemplary embodiment, there is no limitation thereto, and the second right-side operation switch image 36RM may be configured so as to be flipped over in a similar manner. In such cases, the functions allocated to the second right-side operation switch image 36RM may be changed. Furthermore, the left-side operation region image 64M may also be displayed as an animation that is flipped over in a similar manner.

Furthermore, although the icon at the right-side portion of the first left-side operation switch image 34LM is surrounded by an elongated circle so as to emphasize the display as illustrated in FIG. 5 in the present exemplary embodiment, the display of the right-side status image 70M may also be changed in addition to this. For example, configuration may be such that the occupant is made aware that the airflow increase button has been selected by displaying the plus sign in the right-side status image 70M in a larger size.

Furthermore, there is no particular limitation to the number and shapes of the respective operation switches and respective function switchover switches, which may be modified as appropriate.

Although an example of display in the display region V2 has been described in the above exemplary embodiment, there is no limitation thereto, and the corresponding right-side image or left-side image may be displayed in the display region V1.
